The science

Exposure to blue and green light, which are shorter wavelengths, at inappropriate times can make it harder to relax and prepare for sleep, disrupting your body’s natural sleep-wake cycle. In today’s world, artificial light from screens, overhead lighting, and other sources commonly interferes with our sleep. Even small amounts of this light can disturb your natural rhythms by reducing melatonin, a hormone that helps regulate sleep. Our Wind Down™ lenses are specifically designed to block light in the 400-520nm range, helping to minimize this disruption when worn at night and supporting your body’s alignment with its natural circadian rhythm.
